Special Containment Procedures: SCP-3666 is to be contained in a secure holding cell, a 6 m x 6 m x 6 m room of a gold and steel alloy. There must be video surveillance at all times, to monitor subject and be altered to any escape attempts. Pictures must be taken frequently, to see if there is any noticeable change. Going into the cell is prohibited unless it is to feed or study the subject. There must be no more than three (3) D-class personnel inside the cell at one time; they must have tranquillizer weapons and be accompanied by two (2) security personnel in case the subject attacks. Food is to be bought every 6 hours

OK what I don't get is why there need to be any D-class. Why not just have guards with guns and tranquillizers?

Description: SCP-3666 is a humanoid creature measuring approximately 2 meters in height. Subject shows little muscle mass. Subject's front top teeth are two (2) times the norm of an average human and sharpened to points. It is also to be noted that the teeth are stronger than human teeth.The subject's head comes from its chest. Everything else remains similar to an average human, with the exception of its eyes and its arms. The eyes are grossly not sure if right word to use, and I don't really understand what you are trying to say with this. missing, with the exception of red, luminescent dots in its socket. The arms are extremely out of proportion, which measure approximately 1.5 meters each. Subject's only clothes are a bloody, white dress.

SCP-3666 is under most circumstances docile but can become hostile when hungry. The subject as been seen as being able to sprint approximately 64 kilometres per hour, and can jump five (5) feet We only use metric measurement in the air. The subjects' skin pigmentation is currently unknown due to its thick black fur that covers all of its body. The subject was found in a forest near Des Moines, Iowa in 2015. The video surveillance cameras indicate the subject often times crawls around, doing very little in its cell.

When hungry, the subject will start screeching, screaming and will try to run out of the cell to eat.

STAFF NOTICE: According to the Draft Forum Guidelines, please do not post your entire draft in the forums. Make a sandbox page, put your draft there, and link it from on this board by editing your first post. An example of a basic draft forum post can be found in the Guidelines. More instructions on how to format an SCP page can be found in the How to Write an SCP Guide.

Why is this expunged? Additionally, you should never hide information in your Special Containment Procedures because that is essential for safe containment. This guide will give you more information about when to hide data, if at all - you don't have to. Finally, it is written as such - [DATA EXPUNGED].

There must be video surveillance at all times, to make sure the subject doesn't escape. Pictures must be taken frequently.

Wait, so it needs footage that is monitored as well as still photos? Why? Monitoring is one thing, although one could argue you just need to make sure the door is secure, and you shouldn't have a problem, but taking still photos doesn't make sense.

There must be no more than three (3) D-class personnel inside the cell, and they must have tranquilizer weapons and be accompanied by two or more guards in case the subject attacks.

Why do D-Class have to constantly be in there? D-Class should only be around scips when they're actually undergoing testing, not randomly. Remember, this is your Special Containment Procedures, not testing procedures. Additionally, we no longer do the numbers in brackets thing - instead, you should write out the number one to nine, then use the digits for 10 and over.

SCP-3666 is a humanoid creature measuring approximately 2.01 meters in height

2.01 meters is not 'approximate' - that is exact, to an actual decimal point.

Subject shows little muscle mass.

Is that important?

The subjects' skull doesn't come from the top of the torso, but from its chest.

I'm having a hard time imagining this - it's also okay to say 'head' rather than 'skull', because I assume it has skin. Humans don't have a skull that comes from 'the top of the torso' - it comes from our neck, and, most importantly, is connected to our spine. If their autonomy is different, especially if it could affect brain activity and movement, that is going to be something The Foundation wants to explore.

Everything else remains similar to an average human, with the exception of its eyes and its arms.

Then talk about its eyes and arms alongside the other anomalous things you've already spoken about.

The eyes are grossly missing

The word 'grossly' in this context is unscientific and not needed. You go on to describe some sort of 'eye', so they're not exactly missing. Glowing eyes are also an overdone trope, both on this site and in other media.

The arms are extremely out of proportion, which measure approximately 1.9 meters each.

How are they out of proportion? As a note, this is sounding a little too much like SCP-096, nearly to the point to some parts being lifted from its description, e.g. -

Your draft -

Subject shows little muscle mass.

SCP-096 -

Subject shows very little muscle mass

The arms are essentially a copy, nearly word for word, of SCP-096 -

Arms are grossly out of proportion with the rest of the subject's body, with an approximate length of 1.5 meters each.

Your draft -

The arms are extremely out of proportion, which measure approximately 1.9 meters each.

Plagiarism doesn't fly here - it's a bannable offence. Whilst you haven't copied it word for word, it is clear where you lifted the concept and basic descriptions from, and that isn't going to fly either - people are going to look at this and see the similarities to SCP-096 instantly. We don't need another one.

Subjects' only clothes are a bloody, white dress.

Clothes don't matter. It would be given clothes if needed. No point mentioning this at all.

Again, lifting concepts from SCP-096 -

SCP-096 is normally extremely docile

Your draft -

SCP-3666 is extremely docile

but can become hostile when hungry.

Hungry for what? You never talk about diet. It would be essential to know what it would eat and when.

This is essentially an proxy of SCP-096, which becomes clearer as the reader reads. It can possibly run faster -

WARNING: Audio Log From Interview 3666-1 Has Been Prohibited From Any One Unless Dr. █████████ Gives Them Permission.

How are people meant to know which doctor to ask for permission, and if someone is lying about getting permission from a doctor if they don't know their name? Also, there is no reason to capitalise the beginning of each word.

All in all, this is a copy of SCP-096. Why it is anomalous and what it does is barely touched upon. There's no story, nothing to keep the reader reading, and it has no identity of its own.

I would suggest to the author to read as many Series 3 and Series 4 articles as possible, to understand how the site has moved on since SCP-096 and similarly popular articles were written. Now, it's a lot more about having a narrative, telling a story (not necessarily a backstory) as it's a form of flash fiction, using a different method than simply writing a story.

Anything that is copied, particularly from popular/well-known SCP articles, is going to stick out like a sore thumb, and it's not going to be received well. Essentially lifting lines from another article is really, really not going to help you as an author.
